摘要: 探讨斑褐孔菌石油醚提取物(PEFP)体外抗肿瘤活性及其机制。采用磺酰罗丹明染色法(SRB法)考察PEFP对人肝癌细胞SMMC-7721、人胃癌细胞SGC-7901、人喉癌上皮细胞Hep-2增殖的影响。倒置相差显微镜、透射电镜观察PEFP作用SMMC-7721后的细胞形态及超微结构的变化;流式细胞术检测PEFP作用SMMC-7721后细胞周期的改变情况。实验结果显示PEFP对上述三种人恶性肿瘤细胞均表现出明显的抑制效果,且呈剂量效应关系,其半数抑制浓度(IC50)分别为52.72、69.18、58.88 μg/mL。取1/2 IC50浓度的PEFP作用于SMMC-7721 48 h后,细胞形态结构及细胞周期发生改变,G0/G1期细胞增多,S期细胞明显减少。PEFP可能通过阻滞SMMC-7721细胞周期于G0/G1期来抑制肿瘤细胞的增殖,具有较明显体外抗肿瘤活性。

Abstract: The objective of this study was to investigate the anti-cancer activity of petroleum ether extracts of Fuscoporia punctata (PEFP) and its in vitro anti-cancer mechanism. The sulforhodamine B (SRB) assay was employed to test the antitumor effect of PEFP on SMCC-7721,SGC-7901 and Hep-2 cell lines.Inverted phase contrast microscope and transmission electron microscopy were used to observe the changes of morphologic and ultrastructure of SMCC-7721 cells after treatment with PEFP.The changes of SMCC-7721 cells cycle were analyzed by flow cytometry (FCM).The results showed PEFP displayed obvious inhibitory effect on proliferation of the above-mentioned cells in a dose-dependent manner.The IC50 values were 52.72 μg/mL,69.18 μg/mL and 58.88 μg/mL respectively.After treatment with PEFP at the 1/2 IC50 concentration for 48 h,the morphology and cell cycle of SMCC-7721 cells showed special changes.The cell cycle analysis revealed that SMCC-7721 cells increased in G0/G1 phase and decreased in S-phase cells.The SMCC-7721 cells were arrested in G0/G1 phase.The study indicated PEFP can inhibit SMMC-7721 cells proliferation by blocking the cell cycle to G0/G1 phase and had relatively obvious in vitro anti-cancer effect.

Key words: Fuscoporia punctata (Fr.) Cunn, anti-cancer, cell proliferation, cell cycle
